Question

wat are electrical springs

Answer 1

Where did you first encounter that term?

Answer 2

spring analogue in electromagnetism (EM) is capacitor C. Spring constant k is equivalent to 1/C. Spring-mass-damper system is equivalent to RLC circuit: R is damper (friction), L is mass (inertia) and 1/C is spring constant. Both cases (mechanical and EM) are described by the same differential equation. The correspondence between mechanics and EM is :
displacement x <--> charge q
velocity v <---> electric current i
force F <---> voltage (e.m.f) V
mass m <---> Inductance L
linear drag coefficient <---> resistance R
spring constant k <---> 1/C reciprocal of Capacitance
kinetic energy mv^2/2<---> magnetic field energy LI^2/2
potential energy <----> electrostatic field energy
